Purpose-In this experiment you will work with seeds that are living but dormant. A seed contains an embryo plant and a food supply surrounded by a seed coat. When the necessary conditions are met, germination occurs and the rate of cellular respiration greatly increase. In this lab you measure oxygen consumption during germination, measure the change in gas volume in respirometers containing containing either germinating or non-germinating pea seeds, and measure the rate of these two different temperatures.
Conclusion: We measured oxygen consumption during germination, measure the change in gas volume in respirometers containing either germinating or nongerminating pea seeds and measured the rate of respiration of these peas at two different temperatures. According to the data, germinating peas have a higher rate of cellular respiration and also according to the data high temperatures have a higher rate of cellular respiration. The results are valid because cellular processes speed up in warmer temperatures because they can utilize more energy.
Summary of data- The higher the temperature, the faster the rate of cellular respiration was. In addition, germinating peas had a higher rate of cellular respiration than non-germinating peas. This was shown by germinating peas producing more oxygen than non-germinating peas and beads.
